Proper Desk Posture - Ergonomics Basics and Practice

Your Desk Setup Is Either Helping or Hurting You

The average office worker spends 6 to 8 hours daily at a desk. Poor ergonomics during this time creates cumulative stress on the spine, shoulders, wrists, and eyes that manifests as pain, fatigue, and eventually injury. Proper setup costs little but prevents significant suffering. Creating an ergonomic home office is essential for remote workers.

Monitor Position

Top of screen at or slightly below eye level. Screen distance: arm's length (50 to 70 cm). Slight downward gaze angle (15 to 20 degrees) reduces eye strain and neck flexion. If using a laptop, an external monitor or laptop stand with separate keyboard is strongly recommended.

Chair Adjustment

Feet flat on floor (or footrest). Knees at 90 to 110 degrees. Hips slightly higher than knees. Lumbar support maintaining natural lower back curve. Armrests at elbow height (shoulders relaxed, not shrugged). Seat depth allowing 2 to 3 finger-widths between seat edge and back of knees.

Keyboard and Mouse

Keyboard at elbow height with slight negative tilt (front edge higher than back). Wrists neutral (not bent up or down). Mouse close to keyboard to avoid reaching. Consider ergonomic keyboard and vertical mouse if wrist symptoms develop. Addressing shoulder stiffness from desk work requires attention to arm positioning.

Movement Breaks

No posture is good posture if held too long. The best posture is your next posture. Stand or walk for 2 to 5 minutes every 30 to 60 minutes. Perform desk stretches (neck rolls, shoulder shrugs, wrist circles) hourly. Consider a sit-stand desk for position variety throughout the day.

Common Mistakes

Monitor too low (looking down strains the neck). Chair too high (feet dangling increases leg pressure). Keyboard too high (shoulders shrug, causing trapezius tension). Phone cradled between ear and shoulder. Crossing legs (creates pelvic asymmetry).

Summary

Ergonomic desk setup is not about buying expensive equipment - it is about positioning your body correctly relative to your tools. Small adjustments to monitor height, chair position, and keyboard placement, combined with regular movement breaks, prevent the cumulative damage that desk work inflicts on the body.
